Neural Network Libraries - Examples

This repository contains working examples of Neural Network Libraries. Before running any of the examples in this repository, you must install the Python package for Neural Network Libraries. The Python install guide can be found here.

Before running an example, also run the following command inside the example directory, to install additional dependencies:

cd example_directory
pip install -r requirements.txt

Docker workflow

• Our Docker workflow offers an easy installation and setup of running environments of our examples.
• See this page.

nnabla-examples-utils (neu)

neu can now be installed as a python package. It provides a wide range of utility functions. For installation and usage, check utils

Interactive Demos

We have prepared interactive demos, where you can play around without having to worry about the codes and the internal mechanism. You can run it directly on Colab from the links in the table below.
